normally nowadays all motherboards are coming with these programs, I have so far tested Asus's software (not on mine though), and it showed exact reading as were on BIOS.
anyway, today i found a website with freeware programs (some might be shareware) about processors, tweaking and cooling,
hope it might be of some help to you.
also also, pizzathehut, you have Asus, and I have tested the software on same motherbaord, why not use your own software? Asus PC Probe is the name of it, must be in your drivers CD.
whats your temperature BTW?
